Abstract: An industrial robot has a base and the mechanical links of a shoulder, arm and hand joined in series with a waist joint, shoulder joint, wrist roll joint and wrist pivot joint. A clutch mechanism is associated with each joint, and continuously spinning shafting extends through all the links and joints. The clutch mechanisms each take power upon electronic command from the shafting to power the joints and move the links relative to each other.
Abstract: An apparatus for both washing and drying an automotive vehicle. The apparatus includes a track gantry that moves along the track and over the vehicle. Water outlets and brushes are on the gantry to wash the car. The apparatus further includes a blower, nozzle, and oscillator. The blower, also mounted on the gantry, expels air onto the vehicle. The nozzle, positioned on the blower, defines an orientation and directs the air from the blower substantially parallel to the orientation. The oscillator periodically changes the orientation of the nozzle and the direction of the air from the blower.
Abstract: An improved central locking system for a desk includes a plurality of stop members mounted on a pivot rod attached to a panel adjacent a series of drawers. One stop member is pivoted in response to a pin drive actuator which moves when driven by a cam associated with a control drawer horizontally adjacent the other drawers.
Abstract: An improved retaining wall construction includes a plurality of prefabricated, substantially upstanding soil retention panels connected together to define a wall facing. Each soil retention panel has a bottom surface with at least one cutout portion for receiving a lifting arm to lift and transport the soil retention panel, a first end having a projecting portion and a second end having a cutout slot. The projecting portion of one soil retention panel engages the cutout slot of anothe adjacent soil retention panel to form a keyed construction joint.Earth is exacavated along a line demarking the wall construciton, and a concrete leveling pad is placed along the line. The soil retention panel is positioned on the leveling pad by means of an apparatus for lifting having lifting arms that are slidably engageable into the cutout portion of the soil retention panel.
Abstract: A method of parenterally delivering aqueously unstable drugs that includes the aqueous dilution of a stable, anhydrous organic solution having the drug dissolved therein. The resulting organic-aqueous solution is physiologically suitable for parenteral delivery into a warm-blooded mammal and contains the drug in an effective dosage concentration per unit volume.
Abstract: An improved shirring device for sausage casing includes a station having opposed shirring wheels for shirring casing onto a mandrel. Opposed jaws positioned for movement transverse to the mandrel operate to engage shirred casing. Both the wheels and jaws are mounted on a slidable platform which is movable axially to transport shirred casing along the mandrel and to compact the shirred casing.

Abstract: An electric discharge surface conditioning apparatus includes a discharge electrode consisting of an assembly of alternating conductive and non-conductive discs which rotate about an axis. The surface of the conductive discs includes a specific pattern of slots to effect a pumping action thereby enhancing the electric discharge efficiency by circulating the fluid away from the surface of the workpiece being machined. A control arrangement for controlling the orientation of the described electrode is provided.
Abstract: A drawer with an interlocking drawer slide mechanism is disclosed. The mechanism includes a pair of slides, each attached to one side of the drawer and mateable with a slide receiver. Each slide receiver has a pair of guide pins. A plurality of slide receiver supports are provided having openings mateable with the guide pins such that the slide receivers are supported by the slide receiver supports. Each slide receiver includes a slide lock having a drawer catch. A pair of rotatable drawer stops mounted on the drawer releasably catch the drawer catch to hold the drawer in the mechanism.
Abstract: A process for continuous production of high molecular polybutyleneterephthalate by direct esterification of terephthalic acid and 1,4 butanediol in the presence of tin- or titanium-containing catalysts at preferred temperatures of 235.degree. to 250.degree. C., and preferred pressures of 0.3 to 0.6 bar during the first stage--with minimal formation of tetrahydrofurane--followed by precondensation and polycondensation at reduced pressure.
Abstract: A two-dimensional coordinate measuring pad for use, for example, to recognize handwriting. A high resistivity sheet is bounded by a lower resistivity border connected to a switched voltage source to cause a current to flow first in one direction and then in a perpendicular direction through the resistive sheet. Potential measurements at an array of precisely predetermined points are employed to generate a set of correction values which are stored in a programmable read-only memory. Thereafter, to indicate the position of an arbitrarily selected contact point on the sheet, the stored correction values for the nearest points are fetched form the memory and combined with the measured values to produce adjusted output values which more accurately indicate the positional coordinates of the contact point.
Abstract: An improved valve bridge assembly and improved method of manufacturing the same, both new and rebuilt, are disclosed. The valve bridge is of the type that actuates the exhaust valves in larger internal combustion engines, such as locomotive diesel engines, and that has oversized lash adjuster sockets due to wear. The method contemplates providing a set of oversized lash adjusters which are chosen for insertion in the oversized sockets. Also, threaded lash adjusters are disclosed.
Abstract: A sausage stuffing machine includes a cylindrical sausage discharge tube which dispenses sausage material into shirred casing stored on the tube. A clipper is positioned adjacent the end of the tube for sealing the filled casing at desired intervals. A casing brake mechanism is provided at the discharge end of the tube and includes an axially translatable ring which fits over the flared end of the tube to engage the shirred casing.

Abstract: A multistage gas fired water heater includes a primary heating tank and a secondary tank mounted vertically over the primary tank with a plurality of primary flues located within the primary heating tank aligned with secondary flues located within the secondary tank. One of the primary flues is constructed to operate as a condensate removal pipe for draining water which forms in the secondary flues. The designated condensate removal pipe prevents water from trickling down the other primary flues or collecting in the flue manifold.
Abstract: The panel lock comprises an elongated housing having resilient wedging means at each end to secure the panel lock in place in a recess in a door, panel or like member. Formed integrally with the elongated housing are a lock housing with a cylindrical opening, a central recessed portion, and a bolt housing. A lock is rotatably secured in the opening in the lock housing. A bolt is slidably positioned in the bolt housing. A spring is operative between the bolt and the bolt housing to bias the bolt outwardly from the bolt housing into locking position. An actuator is slidably secured to the elongated housing and is adapted to engage the bolt. When the actuator is moved in one direction, the bolt is biased outwardly to a latching position by the spring. Movement of the actuator in an opposite direction will move the bolt against the bias of the spring to a release position. Cam means are secured to the lock and are rotatable therewith to lock or to release the actuator.
Abstract: A wrench tool includes a plate defining a handle at one end with a manual grip and a mounting surface for opposed, pivotal gripping jaws at its opposite end.
